Noise suppression assembly and electronic device having the same

A noise suppression assembly, for an electronic device for transmitting and receiving a signal with a wavelength of a Wi-Fi wireless device, and the electronic device having a circuit board and a connector installed on the circuit board, the noise suppression assembly comprising:

• a wiring area located on surface layer of the circuit board and adjacent to the connector, wherein the wiring area comprises at least one electrical contact, a transmission circuit and at least one ground contact, the at least one electrical contact is configured to be in electrical contact with the at least one electrical pin of the connector, the transmission circuit is electrically connected to the at least one electrical contact, and the at least one ground contact is configured to surround the wiring area;
• a conductive cover member having a cover plate and at least one lateral plate, wherein the at least one lateral plate is connected to the cover plate to form a shielded space, the at least one lateral plate is electrically connected to and in contact with the at least one ground contact, so that both the at least one electrical contact inside the wiring area and the transmission circuit are covered and shielded by the conductive cover member in the shield space;
• and
• a plurality of conductive holding members fixed to and in electrical contact with the ground contact, wherein the at least one lateral plate is clamped by the conductive holding members in a detachable manner;
• wherein, the distance between the conductive holding members adjacent to each other is not greater than one seventeenth of the wavelength.
